.application filed August 3, 1921i. Serial No. 489,533;

To all 'aU/rom 'it may concern:

lie it known that l, Demi lflnUsrnnvnLn, a citizen of the United States,and a resident' of llull, in the county of Sioux and State oflowa, haveinvented a new and improved biuspension liafter and Support, of whichthe following is a full, clear, and exact description.

The present invention relates to new and useful improvements in buildingappliances and hardware, and it pertains more particu lai-ly to meansfor bracing the joints of the rafters of hip roofs.

lit is one of the primary objects of the invention to provide means bywhich the rafters of a hip roof may besecured` together `at their jointswithout the use of nails or similar fastenings, except to preventrelative movement of the members at the joint.`

it is a further object of the invention to provide means by `which thejoint may be tightened from time to time as coniilitions require.

lt is a further object of the invention to so construct a device of thischaracter that it .is applicable to hip roofs regardless of the angleofthe rafters.

lit is a still further object ofthe invention to so construct a deviceof this charzuxter as to render the same adjustable to angles of raftersof varying` degrees.

lWith the above and other objects in view, reference had to theaccompanying drawings, in whichlligure 1 is a side elevation of the'joint of the rafters of a hip roof showing the irnproved device and itsmethod of application in actual practice. i

Fig. 2 is a vertical sectional View taken on the line 2-2 of Fig. 1, andshowing the device in rear elevation, a portion of one of the members ofthe device being broken away.

.Referring more particularly to the drawings, the reference character 5designates the vertical rafter, and (i designates the horizontal rafterof a hip roof. lit is to be under* stood that the roof supported. bythese rafters and that there are a sutlicient number thereof to provide:i proper support for the roof.

Secured to the reiter 5 upon opposite sides thereof, by means of a boltor the like i", are straps S, :1nd said straps 8 are adapt-ed to extendinwardly of the rafter in a siibstantialliT horizontal plane.

Secured to each of the rafters 6 bv means of arbeit 9 or the like, areoppositelywdisposed depemling` stra-ps 10, and said straps 10 dependadjacent their corresponding strap 2% and have their free end lying` inpixtiqiosition tothe inner free end of their respective free strap 8, asmore clearly shown in lfig. 1. Extending through the free ends of thestraps 8 and 10 is asingle bolt 12, and surrounding` said bolt 12 is atubular sleeve 13, by means of which the straps S and 10 are preventedfrom buckling' or bending to, such a degree vthat tliej,v would slidealongthe bolt 12 in either direction.4

Suiiniiinli1i,g the sleeve 13 is a linlr 1li, and pivotally connected insaid linlr 14, is a screwsthreaded eye bolt 15, a nut 16 having;engagement with the threaded end 17 of said eye bolt 15. The referencecharacter 2() designates a rigid angular member, and in use two of thesemembers are employed. Each of these member-sis provided in the ree endsoi'- its legs, with aA series of openngs 21, and said openings areadapted lto eceive bolts 22, by means of which the rigid angular membersare secured to the rafters and l. 'lhcse angular members are connectedat their apexes by a transversely extending); rigid member 23. Theangular niembers 2() and the transverse rigid inember 2? are preferably`formed of anele iron and the rigid member .iis secured to the angularmembers by means of bolts or the like The transverse rigid member 23 isadapted to receiveV the threaded end of the eye bolt 15 as indicated bythe reference character 3() in Fig. l, and the nut 1G is adapted toengage the transverse rigid memA ber in order to tighten the eye bolt15.

The reference character 31 designates a strap or brace which is securedin position by the heretofore mentioned bolts 22, and it will be notedfrom Fig. 1 that said strap or brace Bl embraces the straps 8 and l),and prevents bending` thereof when the device is being positioned.

rilhe device functions in the following manner:

rlhe members S and 10 are secured in position by means of their bolts i'and 9, re spectively, after which the bolt 12 and the sleeve 13 arepositioned with respect to these members 8 and 10. After this has beendone, the angular members 2O are positioned and the eye bolt is passedthrough the rigid transverse member 23, after `which the nut 16 isthreaded upon the threaded end 17 of the eye bolt 15 and the eye bolt 15is pla-ced under tension. As the eye bolt 15 is placed under tension,the strain exerted will cause the joint of the rafters 5 and 6 to assumethe proper position and said rafters 5 and,6 Will be maintained inproper position to support the roof. Simultaneously with the placing ofthe angular members 20, the straps or braces 31 are positioned tooverlap the members 8 and 10, as shown in Fig. 1, and prevent theirbending or buckling under the strain exerted by the eye bolt.

From the foregoing it is apparent that the present device provides meansfor supporting and sustaining the rafters of hip roofs Without employingdriven fastenings, such as nails, and cumbersome vertical braces as isthe common practice. Furthermore, the improved device permits of thetightening of the rafter joints from time to time as occasion mayrequire, and provides a means vvhich is adaptable for use with hip roofsof various degrees of angle.

I claim:

1. In combina-tion With the rafters of a hip roof, a plurality ofmembers rigidly secured to said rafters and extending inwardly thereof,rigid means connecting said members, angular members pivotally securedto the rafters, and tension means connecting the firstunentioned memberswith the rigid angular members, as and for the purpose set forth.

2. In combination With the rafters of a hip roof, a plurality ofinwardly-projecting members arranged in triangular form, said membersbeing pivotally secured to the rafters, rigid means connecting saidmembers, a plurality of oppositely disposed angular members pivotallyconnected to the rafters, a rigid member connecting said angularmembers, and tension means connected to the first-mentioned members andto the triangular members, as and for the purpose set forth.

3. A brace for the rafters of hip roofs, said brace comprising aplurality of members secured to the rafters of the roof in triangularrelation, rigid means connecting said menibers, angular membersconnected to the rafters of the roof, angularly disposed bracesconnected to the angular members and overlying the first-mentionedmembers, rigid means connecting` the angular members, and tension meansconnected to the first-mentioned members and the rigid means connectingthe angularI members, as and for the purpose set forth.

t. A device of the character described comprising in combination withangularly disposed rafters, a plurality of straps secured to saidrafters on opposite sides thereof, said straps being arranged atsubstantially right angles one to the other, rigid right-angular memberssecured upon opposite sides of the rafters, tension means connecting therigid right-angular members with the straps, and braces connected to therigid right-angular members and overlying said straps, as and for thepurpose set forth.

5. A device of the character described comprising a brace for angularlydisposed rafters comprising a plurality of straps secured to saidrafters on. opposite sides thereof, said straps being arrangedv at anangle one to the other, rigid rightangular members secured on oppositesides of the rafters, and tension means connecting the rigidright-angular members with said straps.
